Abstract
The utility model is dual power supply rising pouring centrifugal vacuum induction fusion casting stove, and its structure comprises vacuum chamber 2, winding drum 3, smelting furnace 4, stopper rod mechanism 5, intermediate frequency insulation power supply 6, precision casting 7, rotating disc 8, seal receptacle 9, belt pulley set 10, rotation motor 11; Advantage: by increasing intermediate frequency holding furnace and adopting stopper rod rising pouring mechanism, slag is made to float over crucible top, clean molten steel flows out from bottom, solve when Foundry Production Aero-Space military affairs thin-walled parts, because the cleanliness factor of mother metal is inadequate, the factors such as the secondary pollution of crucible cause a difficult problem for the phenomenons such as product slag inclusion; The raw material proportion solving therefore series products is comparatively light, and do not reach effect by gravity casting, often thinnest part produces a difficult problem for cold shut.By the product that the utility model is produced, qualification rate is promoted to present 85% by original 30%, for good basis has been established in large-scale production, is more conducive to the demand meeting Aero-Space war material part large-scale production development.
Description
Technical field
The utility model relates to dual power supply rising pouring centrifugal vacuum induction fusion casting stove, belong to Aeronautics and Astronautics, military special material parts technical field.
Background technology
Vacuum induction melting furnace is by electromagnetic induction melting metal under vacuum, generally join induction furnace in vacuum chamber, comprise induction coil and corresponding refractory material and crucible, the intermediate frequency power supply that induction furnace matches, the power of its power supply, the specification of frequency and stove and the material of fusing match with it.
Existing Aero-Space war material part is melted by the foundry alloy of a certain trade mark, when reaching certain technological temperature, casts to the accurate formwork of product.Because the cleanliness factor of mother metal is inadequate, the factors such as the secondary pollution of crucible cause the phenomenons such as product slag inclusion, the raw material proportion of certain product is lighter in addition, (titanium and aluminium accounting large), and that some parts are thinner is thinner when making molding shell, do not reach effect by gravity casting, often thinnest part produces cold shut (molten steel underfill fusible pattern).
Summary of the invention
The utility model proposes dual power supply rising pouring centrifugal vacuum induction fusion casting stove, its object is intended to the problem solving vacuum induction melting furnace product slag inclusion and cold shut, adopt secondary eddy-current heating (insulation), utilize eddy-current heating to produce the principle of eddy current, Slag inclusion is suspended and solves with the uphill casting that stopper rod controls.
Technical solution of the present utility model: dual power supply rising pouring centrifugal vacuum induction fusion casting stove, is characterized in that comprising Pressure gauge, vacuum chamber, winding drum, smelting furnace, stopper rod mechanism, intermediate frequency insulation power supply, precision casting, rotating disc, seal receptacle, belt pulley set, rotation motor; Wherein Pressure gauge is fixed on the top of vacuum chamber, and winding drum is fixed on the sidepiece of vacuum chamber, and smelting furnace and intermediate frequency holding furnace are positioned at the middle part of vacuum chamber, and intermediate frequency holding furnace is positioned at the front lower portion of smelting furnace converter nose; Stopper rod mechanism is fixed on intermediate frequency holding furnace, and precision casting is fixing on the rotating pan, and rotating shaft is established in the bottom of rotating disc, and the rotating shaft end bottom rotating disc is connected with rotation motor by belt pulley set.
Advantage of the present utility model: by increasing intermediate frequency holding furnace and adopting stopper rod rising pouring mechanism, slag is made to float over crucible top, clean molten steel flows out from bottom, solve existing for prior art when Foundry Production Aero-Space military affairs thin-walled parts, because the cleanliness factor of mother metal is inadequate, the factors such as the secondary pollution of crucible cause a difficult problem for the phenomenons such as product slag inclusion; In addition, by adopting centrifugal casting mechanism, the raw material proportion solving therefore series products is compared with light (titanium and aluminium accounting large), and some parts are thinner when making molding shell, do not reach effect by gravity casting, often thinnest part produces a difficult problem for cold shut (molten steel underfill fusible pattern).Thus; by the product that dual power supply rising pouring centrifugal vacuum induction fusion casting stove of the present utility model is produced; qualification rate is promoted to present 85% by original 30%; for good basis has been established in large-scale production, be more conducive to the demand meeting Aero-Space war material part large-scale production development.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of dual power supply rising pouring centrifugal vacuum induction fusion casting stove.
In figure 1 is Pressure gauge, 2 are vacuum chambers, 3 are winding drums, 4 are smelting furnaces, 5 are stopper rod mechanisms, 6 are intermediate frequency insulation power supplys, 7 are precision castings, 8 are rotating discs, 9 are seal receptacles, 10 are belt pulley set, 11 are rotation motors, 12 is vacuum pump set.
Detailed description of the invention
Contrast accompanying drawing 1, dual power supply rising pouring centrifugal vacuum induction fusion casting stove, its structure comprises Pressure gauge 1, vacuum chamber 2, winding drum 3, smelting furnace 4, stopper rod mechanism 5, intermediate frequency insulation power supply 6, precision casting 7, rotating disc 8, seal receptacle 9, belt pulley set 10, rotation motor 11; Wherein Pressure gauge 1 is fixed on the top of vacuum chamber 2, and winding drum 3 is fixed on the sidepiece of vacuum chamber 2, and smelting furnace 4 and intermediate frequency holding furnace 6 are positioned at the middle part of vacuum chamber 2, and intermediate frequency holding furnace 6 is positioned at the front lower portion of smelting furnace 4 converter nose; By the rotary motion of winding drum 3, smelting furnace 4 can be made to complete turndown action, molten steel be poured in intermediate frequency holding furnace 6; Stopper rod mechanism 5 is fixed on intermediate frequency holding furnace 6, and stopper rod mechanism 5 can move up and down, and by coordinating of stopper rod bottom and the dewatering outlet bottom intermediate frequency holding furnace 6, controls molten steel and flows in precision casting 7; Precision casting 7 is fixed on rotating disc 8, and rotating shaft is established in the bottom of rotating disc 8, and this rotating shaft passes vacuum chamber 2 by seal receptacle 9, and the rotating shaft end bottom rotating disc 8 is connected with rotation motor 11 by belt pulley set 10; By power and belt pulley set 10 power transmission of rotation motor 11, rotating disc 8 is rotated, and then in bottom pouring simultaneously, precision casting 7 keep certain rotation.
Its course of work: vacuum melting furnace smelting nut alloy to specified temp reaches certain technological requirement → vert and pours the tundish → unlatching induction coil blocked by stopper rod into and form heating and thermal insulation tundish intermediate frequency power supply, due to eddy-current heating eddy current effect, rotating disc rotation → the rotating speed making the Slag inclusion of molten steel to be suspended on liquid level → to start band sealing under certain power and frequency reaches certain technological requirement → lifting stopper rod, molten steel flows in precision casting, simultaneously, due to the centrifugal action rotated, the molten steel of uniform temperature is made to be full of foundry goods → finally obtain qualified cast product.
